“…This approach categorizes topics by sorting words into clusters with high semantic similarity. Among the topic models, Latent Dirichlet Allocation model (LDA) (Blei, Ng, & Jordan, 2003) is the most established topic model (Lu, Mei, & Zhai, 2011) LDA is a popular technique that has been utilized for different research applications such as opinion mining (Karami & Elkouri, 2019;Hemsley, Erickson, Jarrahi, & Karami, 2020;Karami & Pendergraft, 2018;Karami, Shah, Vaezi, & Bansal, 2020), F I G U R E 1 Word frequency vs word rank-the vertical line shows the position of top-50 words reviewing literature (Shin et al, 2019;Karami, Lundy, Webb, & Dwivedi, 2020), analyzing sexual harassment stories (Karami, Swan, White, & Ford, 2019;Karami, White, Ford, Swan, & Spinel, 2020), exploring medical documents (Karami, Ghasemi, Sen, Moraes, & Shah, 2019) and health-related comments on social media (Karami & Shaw, 2019;Karami, Webb, & Kitzie, 2018).
